Squeal-like sound coming from under the hood

[lspringman]

I have a 2014 that will occasionally make a squealing type sound coming from somewhere under the hood.

I can't easily replicate it. Sometimes it happens when I start the car. Sometimes after I turn the car off. Sometimes when I'm driving down the road, and sometimes when I'm just sitting at a light or I just parked the car.

I had it in at the dealer for something unrelated and asked them about it and even showed them a video so they could hear the sound. Of course, they couldn't find anything.

I was hoping someone else had this issue and can tell me what it may be.

Attaching a video as well from this morning so you can hear it. At one point I reved the engine to see if that would stop it, but no luck.

I'm unable to attach the video, so I hope this url to Youtube works!

Take it to the dealer. They'll find it easily. Your car has a turbo engine which adds another level of complication. Don't procrastinate getting it looked at. Play your video to the service manager.

Thank you. I've already shown the video to the dealer and they didn't know what it was, but I can try again and possibly try a different dealership.

If this is the sedan, check the idler pulley. A number of us have had to have that replaced.
